V.1-3 At the Red Sea, they had been delivered from death through water, now they were being tested by having no water at all! It was water which had delivered them from the enemy’s power, here they had to learn the power of water (in God’s hands) as applied to them personally.
V.6 God’s mercy and care again.
V.7 Just like us! After all the Lord had just done for them, here they were doubting the Lord’s promises.
V.8-16 Joshua broke the power of the enemy, but only while Moses’ hands were raised up, on the hill. We have spiritual enemies (see Eph. 6:12). Our power for victory over these enemies can only come through Christ Who is up in heaven praying for us (see Heb. 7:25).
V.15 “Jehovah-nissi” means “the Lord my banner.”
